(e.g., Bloom, 2000; Heibeck & Markman, 1987). Children's acquisition of a relatively substantial large number of "count nouns" in production promotes comparisons across objects and increased attention to object shape, both of which further accelerate the rate of word learning (e.g., Gershkoff-Stowe & Smith, 2004; Namy & Gentner, 2002; Smith, 2003).

The expression of words around the vocabulary spurt appears to require fewer cognitive resources or less "effort" than the expression of words at the start of the second year (Bloom & Tinker, 2001). Support for this notion derives from Bloom's detailed, microgenetic tracking of the language of 12 children who were seen monthly from 9 months to 2% years of age both in a laboratory playroom setting and in their families' homes (Bloom, 1993).
